I'm not sure what's causing this there is no codes present but back firing inside intake when accelerating under load
Did you do any work on the truck ? Plug wires crossed , burnt ?I'm not sure what's causing this there is no codes present but back firing inside intake when accelerating under load
Intermittent misfire .. possibly weak or damaged plug or plug wire . I know I had a plug the the electro was bent and off center and cause it to intermittently misfire on mid range acceleration . Plug wire break down in high temperatures or get burned from the exhaust and can send spark to a ground area it’s close to or touching .. try opening the hood in the dark ,, no lights around and see if there is any arcing from the plug wires or coil packs . when my plug was misfiring I did get a code though !The engine idols very smooth and under light acceleration it runs very smooth with no misfire only under heavy acceleration does it randomly backfire in the intake manifold
Hahaha ,, helps you bounce a bit doing that …More fun for us if you put your hand on the wires tho.
I’ve heard and read that .. I’ve never had to or even wanted to pull the damn intake ,,,,Stupidest design I’ve ever seen .seen my coil packs 3 times in 3 months, hope I don't see them again for a while. those back inlet bolts suck to get at.

The adventure really begins when you strip the upper Intake bolt on #9.
Try it ???That can’t be fun
I’ll send the truck to you and you can move my coils to a easy access locationTry it ???
